1. What Are Corporate Immigration Services and Why Does My Company Need Them?
Corporate immigration services encompass legal assistance with employment-based visas, green card sponsorship, compliance audits, and international employee transfers. These services ensure your organization meets all federal immigration requirements while building a diverse, skilled workforce. A dedicated immigration attorney helps your company avoid costly penalties, visa denials, and employment-related legal disputes.
2. What Employer Duties Begin after a Petition Is Approved
Approval is a starting line, not a finish. Once a worker begins a sponsored role, the employer must keep the job consistent with what the petition described. Changes to job title, worksite, hours, or pay can require an amended filing before they take effect.
For H-1B workers, the duty is concrete. A material change in the terms of employment usually calls for a new Labor Condition Application and an amended petition, and a move to a new geographic area of employment can trigger the same step. Ending a sponsored worker early carries its own rule. The employer should withdraw the petition with USCIS, and for an H-1B worker it must also offer the reasonable cost of return transportation abroad. Companies that treat approval as the end of the process are the ones that fall behind.
These duties connect into a single flow that runs for as long as the worker stays. Verification records open the file, wage and Public Access File duties keep it current, and amended filings track each change in the role until the worker departs or moves to permanent residence. The sections below walk through that flow, from I-9 records through wage duties to the audits that test them.
3. I-9 Verification and Work Authorization Records
Every U.S. .mployer, sponsoring or not, must complete Form I-9 for each new hire under the Immigration Reform and Control Act. The form confirms identity and work authorization, and the employer must finish it within the short windows federal rule sets. Sponsored employees add a layer, because their permission to work often carries an expiration date.
When work authorization is time-limited, the employer must reverify it before it lapses. A worker who holds an employment authorization document needs a tracked expiration date so reverification happens on time. E-Verify, the federal online check, stays voluntary for most private employers but is mandatory for many federal contractors. New York does not require most private employers to enroll, so a New York company should confirm its own status before it relies on the tool. Sound immigration compliance starts with clean, current I-9 records.
4. The H-1b Public Access File and Wage Duties
H-1B sponsorship carries paperwork that lives outside the petition. After certifying the Labor Condition Application, the employer must build a Public Access File, generally within one working day, and keep it open for public inspection. The file documents the wage, the basis for the prevailing wage, and notice to affected workers.
Wage duties do not pause after filing. The employer must pay the required wage across the authorized period, including certain nonproductive time, and it cannot pass Labor Condition Application costs to the worker if that drops pay below the required rate. The table below shows the core records and how long the employer must keep each one.
| Record | Rule source | Retention period |
|---|---|---|
| Form I-9 | Immigration Reform and Control Act | Three years after hire or one year after employment ends, whichever is later |
| LCA Public Access File | Department of Labor | One year beyond the last date any LCA worker is employed |
| Prevailing wage documentation | Department of Labor | Held inside the Public Access File |
5. How Immigration Audits and Penalties Work
Two agencies drive most enforcement. Immigration and Customs Enforcement reviews I-9 records and usually opens with a Notice of Inspection. The Department of Labor reviews H-1B wage and Labor Condition Application duties, often after a worker complaint. Both can arrive with little warning, so records should be ready before anyone asks.
Certain gaps surface again and again during review:
- Missing, incomplete, or late Form I-9 entries
- Skipping reverification of expiring work authorization
- Failing to assemble the Public Access File within one working day
- Paying below the required wage or shifting Labor Condition Application costs to the worker
- Keeping a worker on payroll after status has lapsed
Consequences scale with the conduct. Paperwork errors draw civil monetary penalties, and knowingly employing an unauthorized worker draws steeper ones, with amounts rising for repeat or willful violations. The Department of Labor can order back wages and, in serious cases, bar an employer from future H-1B filings. Deliberate patterns can carry criminal exposure.
A periodic self-audit is the practical way to catch these gaps before the government does. An employer can review its own I-9 forms against current federal rules, confirm that each reverification date is tracked, and check that every H-1B Public Access File holds the wage and notice records the Department of Labor expects. Correcting a genuine error in the open, and dating the correction rather than backdating it, carries far less risk than leaving it for an inspector to find. Running that check on a set schedule keeps small oversights from compounding into a pattern.
6. Frequently Asked Questions
How many days does an employer have to produce I-9s after an ICE Notice of Inspection?
Federal rule gives an employer at least three business days to produce Form I-9 records after service of a Notice of Inspection. That window is short, and it is not the time to locate missing forms or fix old ones. Employers who keep I-9s organized and separate from general personnel files can meet the deadline without scrambling. When records are incomplete, counsel can frame a lawful correction before the deadline rather than after.
Does using E-Verify remove the requirement to complete a Form I-9?
No. E-Verify runs on top of the I-9 process and does not replace it. An employer enrolled in E-Verify still completes Form I-9 for every new hire, then submits the data to confirm authorization through the system. Skipping the I-9 because E-Verify returned a match is itself a violation. For most private New York employers the program stays optional, so a company should choose it knowingly rather than assume the law requires it.
